Abstract: 770. Henrich, M. Jan. 12. No Patent granted (Sealing fee not paid). Cash registers.-Relates to machines of the kind described in Specification 17,774/06, in which the racks set by the amount levers are in two parts for operating the indicators and the type and totalizing - counter wheels. The racks are now made in three parts so as to permit the locking of them successively in order to ensure accuracy in operating the counters. Drum indicators ; flashes ; interlocking ; drawer mechanism. - The setting - levers 20 raise the racks through the gearing on shaft 15, Fig. 4, at the same time setting the amount on the wheels of the counter. A yoke 22 extending under the setting - levers has a cam extension 33 to engage a pin 25 on a double lever 26, 27, so as to remove the latter arm from locking engagement with an offset 32 on a fan-shaped arm 36 fast on a shaft 19 on which the operating-levers 41, 41<1> are pivoted. Operation of either of the latter throws, by means of a slot 35 and pin 49, a double locking- stirrup 51, 53 into engagement with the racks 4, 5 ; while another arm 63 on the shaft 19, by means of a link 71 oscillates a partly-toothed disk 72 for completing the transfer on the counter. This is mounted in a frame 76 and is held in gear with the racks by the spring 78 except when thrust out by a roll 75 on the frame engaging the cam hub 73 of the disk 72. The levers 41, 41<1> are extended to engage levers 45, 45<1> to release corresponding drawers, and have pins 65 to engage recessed slotted arms 67 on a shaft 70 so as to prevent operation of both levers simultaneously. An auxiliary lever 100 engages the locking arm 27 so as to free either lever 41, 41<1> without setting an amount lever, in case only change is wanted. An arm 101, Fig. 4, on the shaft 73 exhibits the corresponding indicator. The setting of an item upon the amount levers 20 disengages, by means of the yoke 21 and pin 23, Fig. 2, the locking-stirrup 56, 57 of the uppermost racks 4, and operation of the lever 41 or 41<1> throws, by means of an arm 39 and pin 49, the locking-stirrup 51, 53 into engagement with the middle racks, the lower racks being held by the counter-setting pinions until they are disengaged therefrom by the hub cam 73 when the transfer is about to be completed. On the movement of the disk 72, a stud 104 re - sets the yoke 21 and the amount levers, and on the return the lever 63, 64 engages a spring pawl 59 on the stirrup 57 so as to lock the top rack and indicators. An extension on this stirrup operates the indicator shutter. Transfer-mechanism.-The counter wheels are carried on a shaft 59, Figs. 4 and 5, and have tripping-pins 89 to set five-toothed pinions 92 on a countershaft 85 which are integral with ten toothed pinions 88 adapted to engage the next higher wheels and effect the transfer. The countershaft 85 is mounted on a frame 86 pivoted at 87 and raised and lowered by a cam 94 at suitable times to ensure correct action at transfer. The actual transfer is effected by long teeth on the comb 97, which has oppositely-placed short teeth for resetting the pinions on the countershaft 85 on the return movement. The shaft 95 carrying the cam and combs for operating the transfer is driven by a pinion 96 gearing with the teeth on the disk 72.
